Cross-border yard security in Otay Mesa
Trailers, tractors and loads change hands all day on Otay Mesa. Sigma's live agents watch those yards remotely, 24/7, and keep a video record of what comes and goes.
Local and live
Next to California's busiest commercial border crossing
Otay Mesa is San Diego's industrial district on the Mexican border, across from Tijuana. CBRE describes its Land Port of Entry as the busiest commercial port in California and the third-busiest on the U.S.-Mexico border, and trucks generally cross here rather than at San Ysidro, six miles west. SR-905, the SR-125 toll road and SR-11 are the main roads onto the mesa.
More than 23 million square feet of industrial space surrounds the crossing, much of it supporting maquiladora manufacturing in Tijuana. Brown Field Municipal Airport sits 1.5 miles north of the border, and SANDAG and Caltrans are developing a second crossing, Otay Mesa East, along SR-11. The result is a district of truck yards, cross-docks and trailer drop lots, many of them quiet overnight.
Sigma's agents can check trucks in at the gate remotely, seeing each arrival on camera and speaking to drivers through the site's speakers. Parking reports show which trailers are on the lot, and damage inspections and visual seal checks on video record their condition when they arrive and leave. After hours, AI person and vehicle detection flags anyone in the yard, and an agent gives a live, instant talk-down and escalates to police when needed.
On the record: After cargo trailers were stolen in Camarillo on New Year's Eve 2024, the Ventura County Sheriff's Office found them emptied and abandoned in Commerce and near the Otay Mesa Port of Entry, and said the goods' final destinations were in Tijuana. Source: Ojai Valley News, 2025

FAQ
Otay Mesa, San Diego monitoring questions
Can you watch a trailer yard or cross-dock near the Otay Mesa crossing?
Yes. Live agents watch your cameras 24/7, 365 days a year. They handle arrivals at the gate remotely, and overnight AI person and vehicle detection flags anyone in the yard for a live, instant talk-down.
What do your seal checks cover?
Agents do visual seal checks on video as trailers arrive and leave, alongside damage inspections and parking reports. They give your team a visual record; they are not an inspection of the load.
